ISL8033 is a dual integrated power controller rated for 3A per channel with a 1MHz step-down regulator that is ideal for any low power low-voltage applications. The ISL8033A offers 2.5MHz operation for smaller more compacted design. The channels are 180° out-of-phase for input RMS current and EMI reduction. It is optimized for generating low output voltages down to 0.8V each. The supply voltage range is from 2.85V to 6V, allowing for the use of a single Li+ cell, three NiMH cells or a regulated 5V input. It has a guaranteed minimum output current of 3A each when ISET is connected to VDD. The output current of each output is
selectable by setting ISET pin.
